ALBERT EDWARD WALKER, ARTHUR WALKER, AND GEORGE WALKER, OF NORWOODGREEN, NEAR HALIFAX, ENGLAND.

Specification of Letters Patent.

Patented July 31, 1906.

Application filed July 8, 1905. Serial No. 268,794.

T at whom, it may concern:

Be it known that we, ALBERT EDWARD WALKER, ARTHUR WALKER, and GEORGEWALKER, subjects of His Majesty the King of Great Britain, residing at Norwood Green, near Halifax, England, have invented a certain new anduseful Improvement in Weft- Replenishing Looms, of which the followingis a specification.

The invention, while adhering to the principles of automaticweft-replenishing described in our United States Patent No. 738,644,consists in a modification adapted A for use when the compartments ofthe shuttlebox are arranged vertically instead of around a commoncenter, the object being to enable the feeding mechanism of our previousinvention to be used with looms provided with shuttle-b oxes having two(or more) verticallyarranged compartments, as at present used for two(or more) colors of weft, so that such looms can be run simply asweft-replenishing looms, if desired.

In the drawings, Figure 1 is an elevation looked at from the back of theshuttle-box and supporting parts according to our invention. Fig. 2 is asection on line A B of Fig. 1. Fig. 3 is a vertical section on line C Dof Fig. 1, drawn to a larger scale, with the shuttlebox in its raisedand forward position and in the act of receiving a new shuttle. Fig. 4is a similar view to Fig. 3, but with the shuttlebox in its raised andbackward position, the lower compartment being opposite theshuttle-race; and Fig. 5 is also a similar view, but with theshuttle-box in its lowered position in the act of discharging a usedshuttle from the lower compartment.

According to the present invention a shuttle-retaining bar 1 is mountedbetween the end of the going part or lay 2 and the end of thebox-supporting frame 3, opposite the shuttle-box 4, and in front of thedivision 5 between the working compartment 6 and thereceiving-compartment 7 above it. The bar 1 may, as shown, be mounted ina bracket 10, carried by the going part 2 and attached at its inner end(which is bent, as shown, to avoid obstruction to the shuttle) to thebracket 29, supporting the guide-rod 25 of the picker 26. -When theshuttle-box is in the working position shown in Fig. 4, the bar 1 coversthe front of the working compartment 6 a suflicient distance to act as ascreed or guide-bar for the shuttle 8 when weaving, and it also coversthe receiving-compartment 7 a sufficient distance to act as aretainingledge for the shuttle 9 when received from the automaticfeeding apparatus.

A stop-piece 11. is preferably fixed to the box-frame3 to preventanyendwise movement of the shuttle 9 in the compartment 7 when the box 4is in its raised position. The shuttle in the compartment 7 is furthersteadied by the pressure of a fiat spring 12, secured to the upper partof the box-frame and adapted to protrude through a slot in the top 22 ofthe compartment into contact with the shuttle when said compartment isin the position shown in Figs. 3 and 4.

An inclined piece 13, forming a cam-path,

is fixed upon the box-frame 3, vertically between the back of theshuttle-box 4 and the free end 14 of the swell 15 of the uppershuttle-compartment 7, so that as the shuttlebox is reciprocated theinclined piece 13 acts upon the swell 15 and removes it from thecompartment when the latter is in the positions shown in Figs. 3 and 4;but when the receiving-compartment 7 1s in the working position and thelower or working compartment 6 is discharging the used shuttle 8 theswell15 will have ridden down the lower side of the inclined piece 13and have been pressed inward by its spring 16 into contact with theshuttle 9 to steady the latter (as shown in Fig. 5) before it is shotinto the shuttle-race of the loom by the picker in the well-knownmanner. The swell 20 of the compartment 6 is not acted on by thecam-piece 13; but the latter is provided with an auxiliary inclinedpiece 27, the incline of which is less than that of the piece 13, beingso proportioned that when the used shuttle in the working oompartmentis, with the latter, lowered from the position shown in Fig. 4 into thedischarging position (shown in Fig. 5) the swell 20 (which haspreviously been pressed outwardly against its own spring-pressure by theused shuttle 8) as the compartment commences to lower, and thus removethe shuttle from the retaining pressure of the bar 1 is prevented fromprematurely pushing'the shuttle out of the compartment by the auxiliarycam-piece 27, over which the free end of said swell 20 must ride. Whenand immediately the compartment has reached its proper position for thedischarge of the shuttle 8 said swell by the action of its spring 28suddenly slides down the incline of the campiece 27, exerting acomparatively quick pressure on the shuttle and discharging the latterfrom the compartment at the proper time.

The shuttle-box 4, which is carried by the going part 2, is verticallyreciprocated by means of the rod 17 and mechanism similar to thatemployed to revolve the rotary shuttie-box and described in ourabove-mentioned United States patent. Stops 18 are provided edge 23 ofthe retaining-bar 1 may also be curved to pass readily under the shuttleon the forward movement of the going part 2, as shown in Fig. 3.

The operation of the invention is as follows:

" The full shuttle is fed from the hopper 21 into the u per or receivingcompartment 7 of the shutt e-boX by the automatic feeding mech anism,previously referred to, on the forward movement of the going part, (seeFig. 3,) the upwardly-curved top 22 of said compartment passing over theshuttle, the opening of the compartment 7 being greater than the depthof the shuttle, and simultaneously the curved edge 23 of theretaining-bar 1 passes under the shuttle. At the end of such forwardmovement the shuttle 9 falls below the retaining-bar 1 and is therebyretained in the compartment 7 as the going part retires into theposition shown in Fig. 4. Afterward at the required time the downwardmovement of the shuttle-b OX takes place, and the compartment 7 islowered into the temporary working position shown in Fig. 5, and theused shuttle in the lower or working compartment 6, being freed from therestraint of the retain ing-bar and aided by the pressure of the swell20, is discharged from its compartment by the action of the swell 20, asalready described, assisted by the vibration of the going art, and fallsinto a chute 24, conveniently placed for the purpose. Immediately afterthe discharge of the used shuttle the full shuttle in the uppercompartment, which is now in the lowered or working position, is shot bythe picker 26 into the shuttle-race, and the shuttlebox is then returnedto its former raised position in readiness both to receive a new shuttlein the compartment 7 from the feed-hopper 21,

v Fig. 3, and to bring the lower compartment 6,

recently vacated by the used shuttle, in the working position to receivethe full shuttle on its return from the shuttle-race, and in thisposition the shuttle-box remains until such time as the full shuttlebecomes used, when the reciprocating mechanism is again auto maticallyactuated and the above-described.

as a retaining-ledge for the shuttle when re-- ceived from saidshuttle-feeding device.

2. In weft-replenishing looms the combination with avertically-reciprocating shuttle-box having several compartments andswells, a shuttle-feeding device and a going part, of ashuttle-retaining bar carried by said going part to act either as ascreed only or both as a screed and a retaining-ledge for the shuttleaccording to the position of the shuttle-box, and means carried by saidshuttle-box to operate said swells to control the admission, retention,and discharge of the full and used shuttles respectively to, in, andfrom said compartments.

3. In weft-replenishing looms the combination with avertically-reciprocating shuttle-boX having several compartments andswells, a frame for said shuttle-box a shuttlefeeding device and a goingpart, of a shuttleretaining bar carried by said going part to act eitheras a screed only or both as a screed and a retaining-ledge for theshuttle according to the position of the shuttle-box, and an inclinedpiece carried by the shuttle-box frame to operate said swells to controlthe admission, retention, and discharge of the full and used shuttlesrespectively to, in, and from said compartments.

4. In weft-replenishing looms the combination with avertically-reciprocating shuttle-boX having upper and lowercompartments, a frame for said shuttle-box a shuttlefeeding device and agoing part, of a shuttleretaining bar carried by said going part to acteither as a screed only or both as a screed and a retaining-ledge forthe shuttle according to the position of the shuttle-box, means carriedby the shuttle-box frame for preventing endwise movement of the shuttlewhen in the upper compartment, and an inclined piece also carried by theshuttle-box frame to operate said swells to control the admission,retention, and discharge of the full and used shuttles respectively to,in, and from said compartment.

5. In weft-replenishing looms the combination with avertically-reciprocating shuttle-boX having several compartments, ashuttle-boX frame, a shuttle-feeding device and a the shuttle-box, meanscarried by the shuttle-box frame and comprising a stopiece and a flatspring for preventing end wise movement and for steadying the shuttlewhen 5 in the upper compartment, and means carried by the shuttle-box tooperate the swell of the shuttle-box compartments to control theadmission, retention, and discharge of the full and used shuttlesrespectively to, in, and 10 from said compartments.
